DETAILED DISCLOSURE

Referring to FIG. 1 there is shown an embodiment of a motorizedskateboard with a remote power supply 31. A power cord 29 connects theskateboard 10 to the remote power supply 31. The board can be controlledby a wired remote or wireless remote 30. The motor 18 is used as a meansto drive the wheels and propel the skateboard. In a specific embodiment,the motor 18 can also be used to brake the skateboard. In a specificembodiment, the battery pack can be carried in a backpack. In otherembodiments, the rider can attach the battery pack to a belt, other itemof clothing, carry the battery pack due to gravity holding the batterypack to the rider's body (such as a vest or necklace type structure),use leg bands and/or armbands, or use other structures for allowing thebattery pack to be carried by the rider. In other embodiments, smallerbattery packs can be mounted to the deck, truck, electronics bracket, orother location on the skateboard. Having an on-board battery(s) cansimplify operation for the rider and can also be used to supplement, ortake the place of, remotely-carried batteries. Embodiments of themotorized skateboard can incorporate the use of other power sources,such as, but not limited to, a fuel cell or combustion engine.

Referring to FIG. 2-4, there is shown an embodiment of a motorizedskateboard 10 having a riding platform 11 having two skate trucksattached, a front truck 12, a rear truck 13. Each truck can have a truckplate, a hanger, a bushing, a kingpin that connects the hanger, bushing,and truck plate together, and an axle housed in the hanger. Connected toeach skate truck are two wheels, front right wheel 14, front left wheel15, rear left wheel 16, rear right wheel/drive wheel 17. Attached to therear truck is a motor 18. Preferably, the motor is attached in parallelto the rear truck. Specific embodiments attach the motor to the hangerof the truck and, preferably, with the axle of the motor parallel to theaxle housed in the hanger. In alternative embodiments, the motor 18 canbe attached to the platform 11. The motorized truck can be installed onthe front of a board, the back of a board, or on both the front and theback of a board. Either the right wheel, the left wheel, or both wheelsof each motorized truck can be driven. In the embodiment of FIGS. 2-4,the shaft of the motor has an attached pulley 19 that rotates on thesame axis as the motor. The motor axis and pulley axis are parallel withthe axis of the wheel. In other embodiments, the motor can be operatedwith the motor axis at various angles with respect to the axis of thewheel, and/or the axis of the pulley can be non-coaxial with the motoraxis, such as by the use of various gears and/or drive shafts known inthe art. The motor pulley 19 drives a belt 21 that runs between the reartruck 13 and motor 18. The belt 21 turns the drive pulley 20. The drivepulley 20 then turns the drive wheel 17 by means of an interlockingdrive wheel hub. In another embodiment, the drive hub's features can bebuilt into the wheel's design to eliminate the use of an interlockingdrive hub. Additional embodiments can utilize alternativeinterconnections to transfer the power of the motor to the rear truck,such as one or more gears, chains, or other linkages, and can also,optionally use one or more clutches. Further embodiments, where thedrive pulley is fixed to the truck axle and the wheel drive hub is fixedto the wheel and to the truck axle, rotate the wheel by rotating thetruck axle by rotating the drive pulley and then the rotation of thetruck axle rotates the wheel.

Referring to FIG. 12-14, there is shown an embodiment of a motorizedskateboard 10 with the electronics bracket 23 mounted to the top of thedeck. The electronics bracket 23 houses the electronics 24 and ismounted to the top of the deck 11 with bolts 25 that secure the truck 13to the deck 11 as well as the electronics bracket 23. The bracket can beopen or enclosed and can be mounted on either the front, back, or bothends of the board.

Referring to FIG. 15-18, there is shown an embodiment of an electricskateboard with a bottom-mounted electronics bracket 26. Thebottom-mounted electronics bracket 26 protects the electronics 24. In aspecific embodiment, the bottom-mounted electronics bracket 26 issecured to a mounting plate 27. Alternatively, the bottom-mountedelectronics bracket 26 can be secured to the deck 11. The mounting plateis attached to the board with the same bolts 25 that secure the truck 13to the deck 11. The bracket can be open or enclosed and can be mountedon either the front, back, or both ends of the board.

Referring to FIG. 19A-19D, there are shown diagrams of the electronicsthat can be utilized in specific embodiments. Other interconnectionschemes can also be used. These figures help to illustrate a few keyembodiments and demonstrate the variety of component and powerconnection locations that are possible. FIG. 19A shows a diagram for a“bare bones” electrical system for a skateboard of a specificembodiment. Referring to FIG. 19B. In a specific embodiment, the ridercarries the battery 32 and connects it through a power cable to theboard at the safety connector 33. The safety connector 33 disconnectsthe battery from the board automatically if the rider leaves the board.This lowers the risk of damage to both the rider and the equipment.Other automatic shut off apparatus can be utilized to dc-energize themotor, as desired, such as a pressure detector that detects when therider is off the board. FIG. 19C shows a specific (and preferred)embodiment where the board has integrated wiring with safety connectorsat each end. This allows for battery connection at the front or the backof the board. Additionally, the interchangeable aspect of this systemallows for placement of electronic components in various locations andarrangements. Other embodiments include board-mounted batteries(including multiple batteries). FIG. 19D shows a specific embodiment inwhich the board wiring is used to connect the motor to the electronicspeed control (ESC). In other embodiments, multiple motors can bepowered and controlled by shared or separate electronic components.

Referring to FIG. 20, FIG. 21A, and FIG. 21B, there is shown anembodiment utilizing a floating-axle truck 13 with a removable motormount 36. “Floating-axle” refers to any skate axle that rotates onbearings in the same motion as the wheel. The motor mount can be held inplace by a snap ring 53 and further secured by a setscrew 45. Ifpreferred, a bead of weld 55 can permanently fix the mount to the truck13, such as to the hanger of the truck. Alternatively, the motor mountcan be bolted onto the hanger directly. In the embodiment of FIG. 20 andFIGS. 21A-B, the end 56 of the hanger and the motor mount 36 havecorresponding geometry, such as a hexagon shape 51 shown in FIG. 21B, toalign the motor mount with respect to the hanger and to resistrotational forces such that the motor mount and hanger do not rotatewith respect to each other. The angle of the motor mount, with respectto the hanger, can be set to any degree by modifying the design of themotor mount's corresponding geometry. In a specific embodiment, notshown, the motor mount can incorporate an adjustable, e.g., rotatable,aperture through which the end of, or other portion of, the hangerinterconnects with the motor mount, where the rotation of the adjustableaperture can be fixed at a desired position. The motor mount can berotated with respect to the hanger to a position where the motor is onthe other side of the hanger. This style of motor mount can be used forsolid-axle or floating-axle skateboard trucks. Enough room is availableon each truck to allow for dual-motors. Specific embodiments can utilizedual motors. In alternative embodiments, the motor mount interconnectswith another portion of the hanger. In a further embodiment, a coupler(not shown) can interconnect with the hanger, such that the coupler andhanger do not rotate with respect to each other about the axis of thehanger, and then the motor mount can interconnect with the coupler toprevent rotation of the motor with respect to the hanger.

Referring to FIG. 22, there is shown an embodiment utilizing afloating-axle truck 37. Again, “floating-axle” refers to any skate axlethat rotates on bearings in the same motion as the wheel. A motor mount36 is attached to the truck's hanger 37. The end of the drive pulley 20interlocks with the keyed drive hub 35. The drive hub 35 is fixed to theinner portion of wheel 17 nearest the motor. The drive pulley 20 isfixed to the axle 34, which makes adjusting the axle nut easier. Inalternative embodiments the interconnection of the drive pulley to theaxle can allow “slippage”, such as by the use of a clutch or torquebased mechanism that allows the pulley and the axle to rotate withrespect to each other (e.g., an attachment element can mount to the axleand a clutch can interconnect the drive pulley to the attachmentelement). In still further embodiments, the drive pulley and axle can befree to rotate with each other and can, optionally, incorporate bearings(not shown). In a further embodiment, the interconnection of the drivehub 35 and the drive pulley can incorporate a clutch in a similar manneras described for the interconnection of the drive pulley and axle. Thefloating axle is supported in the truck by bearings 38 at both ends ofthe floating axle truck. The floating axle design can also be adapted todrive both wheels simultaneously and/or differentially.

Referring to FIG. 23, there is shown an embodiment utilizing asolid-axle truck. “Solid-axle” refers to any skate axle that allows thewheel to rotate around it. The solid axle 42 in FIG. 23 is fixed inposition with respect to the hanger such that the axle does not rotatewith respect to the hanger. The solid-axle truck utilizes a drive pulleywith bearings 41. The drive pulley with bearings 41 interlocks with thekeyed drive hub with bearings 40. On the solid axle truck 39 the drivepulley with bearings 41 and the drive hub with bearings 40 rotate aroundthe stationary axle 42. In another embodiment, the drive pulley withbearings has specific geometry to engage with a bearing-mountedskateboard wheel.

Referring to FIG. 24, there is shown a wheel hub for a floating-axletruck. The drive hub 35 is a two part assembly: a female end 43 and amale end 44. FIG. 24 shows an embodiment of a hub assembly withhexagonally shaped interactions that transfer torque to the wheel viathe female end and the male end such that the torque is distributed toboth sides of the wheel. The hub's interlocking shapes can be differentthan those shown. In a specific embodiment, the drive pulley can beintegrated with the female end such that the male end interconnectsdirectly with the drive pulley. The hub interlocks with the drive pulley20. The shape of the interaction between the drive pulley and drive hubcan be varied. The drive pulley 20 is fixed to the floating axle 34 bytwo setscrews 45 as seen in FIG. 24, or can be fixed by other means,such as collet action or keyed parts to lock the sprocket to the axle.Locking the sprocket to the axle allows for two-wheel-drive applicationsand aids in convenient removal and adjustment of the axle nut. The hubscan be fixed to the wheel through means of, for example, collet-typeradial force, splines, and/or adhesive. In another embodiment, the drivehub and/or the drive pulley has specific geometry to directly engagewith a skateboard wheel's features. In a specific embodiment, the drivepulley can rotate freely with respect to the axle, for example viabearings, and rely on the engagement with the wheel drive hub, or thewheel's features, to rotate the wheel.

Referring to FIG. 25, there is shown an embodiment of a wheel hub for asolid-axle truck. The drive hub 35 is a two part assembly: a female end43 and a male end 44. The drive hub 35 interlocks with the drive pulley41. The drive pulley 41 is suspended by bearings 46 on the solid axle42. The hubs can be fixed to the wheel through, for example, acollet-type radial force, splines, and/or adhesive. Alternatively, themale end 44 may be replaced with a bearing if the interaction betweenthe female hub and the wheel has adequate radial shear resistance. In aspecific embodiment, the drive pulley can rotate freely with respect tothe axle, for example via bearings, and rely on the engagement with thewheel drive hub, or the wheel's features, to rotate the wheel.

Referring to FIG. 26, there is shown an embodiment of a lockable truck.The truck has a lock pass-thru hole 48, which is a common hole throughthe base plate 50, deck and/or electronics bracket. A security cable 47can be threaded or pushed through the lock pass-thru hole 48 to securethe skateboard 10 to another object. Chains, U-locks, specialized racks,and other types of locking equipment can be used instead of the securitycable as long as it can fit through the pass-thru hole or attached toanother structure that can fit through the pass-thru hole.

Referring to FIG. 27, there is shown an embodiment of a lockable truck.The lock pass-thru hole 48 is in the base plate 50 of the truck 49.

Referring to FIG. 28, there is shown an embodiment of a lockableelectronics bracket 27 with a lock pass-thru hole 48.
